Disposable Shielding Gas Cylinders for MIG Welding: Co2, Argon/Co2, Pure Argon(100 l = £22.17)
Argon, CO2 and Argon/CO2 mix mini shielding gas cylinders which are typically used with portable MIG and TIG welding machines. They feature 10mm fittings and provide a cost-effective alternative to stationary industrial size gas cylinders.
Many MIG welding applications lend themselves to a variety of shielding gas choices, and you need to evaluate your welding goals in order to choose the correct one for your specific application. The cost of the gas, finished weld properties, preparation and post-weld clean up, the base material, weld transfer process and your productivity goals all need to be taken into account when selecting a shielding gas.
If you are interested in weld quality, appearance and reducing post-weld clean up, Argon/CO2 mix will provide a more desirable combination of arc stability, puddle control and reduced spatter than pure CO2. This mixture also allows the use of a spray transfer process, which can produce higher productivity rates and more visually appealing welds.
Mini regulators for these bottles are also available, see our listing as well as hose to suit.
Using Argon in the welding process produces a narrower penetration profile, which is useful for fillet and butt welds. If you’re welding a non-ferrous metal — aluminium, magnesium or titanium — you’ll need to use 100 percent Argon.
Pure CO2 gives very deep weld penetration and is useful for welding thick material; however, it also produces a less stable arc and more spatter than when it is mixed with other gases. It is also limited to only the short circuit process.
We also supply pure Argon, and if you’re welding a non-ferrous metal — aluminium, magnesium or titanium — you’ll need to use 100 percent Argon but Argon is also excellent with stainless steels. Because it produces a wide, deep penetration profile, Argon also produces a narrower penetration profile, which is useful for fillet and butt welds.
